Frequently Asked Questions
Straight answers. No marketing speak.
Privacy & Data
Does the Dosii app collect my calculator data?
No. The iPhone app performs calculations locally, requires no account, and does not send vial, dose, water, calculator, or health values to the marketing website or Meta. See our privacy policy.
Does this website use measurement?
When a valid public Meta Pixel ID is configured, this marketing site records one PageView per load and one AppStoreClick per App Store link activation. Event fields are limited to sanitized campaign and creative identifiers. Advanced matching, Conversions API, and retargeting are not used for this phase.
What happens to my data if I delete the app?
It's gone. Everything is stored locally on your device. Deleting the app deletes all your data permanently.
Is there a cloud sync or backup?
No. This is intentional. Your dosing data never touches a server.
Pricing
How much does Dosii cost?
$9.99, one time. No subscription, no in-app purchases, no ads. You own it forever.
Why one-time pricing instead of a subscription?
A calculator should not charge rent. You pay once, it's yours. Every update included.
Is there a free trial?
No, but the App Store offers a refund policy if Dosii isn't what you expected.
The Calculator
What does Dosii actually do?
You enter three things: your vial size (mg), your dose (mg or mcg), and how much water you added. Dosii presents the mathematical result on a syringe scale. It also calculates cost per dose if you enter the vial price.
What syringe sizes are supported?
30-unit, 50-unit, and 100-unit insulin syringes. The syringe visualization updates to match whichever you select.
Does it work with pre-mixed compounds like testosterone?
Yes. Pre-mixed mode lets you enter concentration (mg/mL) and vial volume directly, skipping the reconstitution step.
What are the water suggestions?
When you enter a vial size and dose, Dosii suggests BAC water amounts that place the calculated result on an even syringe tick.
Getting Started
What platforms is Dosii available on?
iOS only.
Do I need to create an account?
No. Open the app and start calculating. Zero onboarding.
How do I get started?
Download from the App Store, enter your vial size and dose, and Dosii presents the calculated result on the selected syringe scale.
